To all 'whom it may concern;

Be it known that l, Rei, a citizen or' the United liliniieapolis, in the county oi yState of Minnesota, have inve new and useful Improvements and l do hereby declare the t'ol a fell, clear, and exact descripti. invention, such as will enable othe in the art to which it appertains and use the sanie.

lily invention relates to tractors, and incre particularly of the type discloi j. and claimed in niy pending application, Serial Number 35,191, filed June 21st, l9l5, and entitled Tractor. ln the drawings oi my said application, the main longitudinal iiieiiiloer oi the tractor frame is in the form of a long and quite large and heavy tubular arrn. rilie present invention consists in ntilizing this tn oiilar arm as an exhaust mail er tor the internal combustion or explosive engine of the tractor.

lin the accoinpanying drawings which li. ljzia'rsonoii, residing at iinepin and d certain Tractors; ring to he i of the make illustrate the invention, like characters indicate like parts throughout the several views. 1,/ i

Referring 'to the drawings; Figure l is a plan view showing the tractor which, except as noted, is identical with that disclosed in my said pending application;

Fig. 2 is a section taken on the line m2 m2 of Fig. l;

Fig. 3 is a detail in horizontal section on the line m3 m3 of Fig. 2; and

Fig. 4l is an end elevation ot the tubular arm which is shown in section iii Fig. 3.,

Of the parts ot the tractor, it is, for the purposes of this case, only desirable to pan ticularly note the rear frame casting l having the forwardly projected tubular arm il.,

which is preferably oic heavy Wrought iron or steel pipe rigidly secured at its rear end to the freine casting l., and at its front end rigidly secured to a front Wheel hearing bracket 5, tothe prongs of which a relatively small front guide wheel 9 is journaled. The rear traction Wheels 3 are journaled on axially alined triiiinions of the rain'e casting l. The explosive engine, which is indicated, as an entirety, by the numeral 16, has its cylinderand bed casting rigidly secured to the trame casting l, and,

s; skilledv 'as shown, is a two-cylinder opposed enginel with the ares of its cylinders extended in e forward and rearward direction. This en- Pateiited Apr 9, illlh l gine drives the traction Wheels 3 through suitable transmission mechanism, not necessary for the purposes ot' this case to oonsider, hut which are fully described iii my, said pending application, but which, liovs'-,l ever, constitute no part of the present in` vention. The parts so tar indicated by the numerals ai indicated hy corresponding numerals in niy said pending application.

Coming now to the feature of my inveiin tion, it will he noted that the exhaust ports from the tiro cylinders of the engine4 are connected directly to `branch pipes a and'ol,

which unite iii a coinmoii exhaust pipe as that taps and opens into the rear portion of the tubular arm l. The front end of the said tubular. arin '-l. is partly closed by a per forated head Zi, which, as shown, is held-in place by a long init-equipped rod c that will extend through the closed rear end head of the said tubular arin.

lt will thus he seen that the tubular arm Ll, in addition to its primary function. wherein serves as a nia-in freine member, also serves as an etlicieiit muffler of large capacity. By this arrangement, not only isv the construe' .on oi' the tractor siiiipliied'VV and reduced in cost, hut the ordinaryat1 taclied inuiler, which is always more or less in the Way, is eiitirel done away with.

lt will loe noted tiat the engine is supported entirely upon the frame casting l, and that the tubular arm 4 projects forward therefrom; lhe engine being locatedl directly upon the trame casting l, substantially all of its Weight is taken directl f hytlie traction Wheels through the journa s onl the traine casting. The tubular arin 4, therefore, is not required to support the eli-,- giiie, but it serves as a reach connecting the :traine casting l with the support for the steering Wheel, and it also serves as a, muf- 'ler receiving the exhaust from the engine. Being located in front of and being entirely independent not-subjected to the heat that is generated by the motor and transmitted bythe motorv traine. There is a marked advantage in this construction over a construction in which the inotoror engine is located upoi a. tubular trame that serves as a mower.

or" the engine or motor, it is` substantially counterupon mid wheel 'trumions, and ex- 'om said engine and i'a portion of Said tubul arm scrvesvas n reach ment with one of the S nding f1 Lu am@ and th *fi Vfl n zum h vu from, 1d S119 ,si grunt u 1'@ as a mu'er for its enaux my H B. HRTSOUGH.
